Z '0 all whom it may concern:

Be it known that I, EZRA Dixon, a citizen,

of the United States, residing at Bristol, in the county of Bristol andState of Rhode Island, have invented a new and useful Improvement inTop-Roll Saddles, of which the following is a specification.

This invention relates to certain new and useful improvements in a toproll saddle, and especially to that type employing a back saddle havingonly a bearing on the back roll, the middle roll being untouched byeither the front or back saddles, and while the invention isparticularly adapted for this type it is also capable of embodiment inback saddles bearing on either the back or middle rolls or both, such asis illustrated in my Patent No. 10877 3 1, issued February 17 191 1.-

The invention resides in the formation of a lock between the front andback saddles which will necessitate relative movement other thanrotation about the axis of one saddle by the other saddle, this beingaccomplished in the present instance by forming a knob on the end of thefront saddle to enter a socket or opening in the back saddle on relativeangular movement for connecting. the two saddles.

The invention further resides in the features of construction, and thearrangements and combinations of parts described in detail in thefollowing specification and succinctly defined in the appended claims,reference being had to the accompanying drawings vrherein Figure 1 is aside elevation of the improved saddle construction as applied to aspinning machine, the latter being in fragment.

Fig. 2 is a detailed section on line 22 of Fig.1.

Fig. 3 is a fragmentary side elevation of the saddle constructionshowing particularly the improved lock, and

Fig. 4: is a top plan view of that portion 7 of the saddle illustratedin Fig. 3.

Referring more in detail to the drawing, the numeral 1 indicates thefront roll saddle which rides the front roll 2 and is formed with arearwardly extending shank 3 termibeing peripherally recessed, as at 5,adjacent and in advance of the knob to reduce the diameter of said shankat this particular point.

. Y Specification of Letters Patent; I t t dM 7 191 The back saddle isadapted to, ride either theback roll 6 or the middle r0117, a laterallug .8 being formed-on theeshank 3 between the recess and. the saddlebodyproper past which the back saddle is movable for assuming operativerelation with either roll. '2 This back saddle 9 has suitableroll-straddling means 10 on its lowerside and is pro-; vided with. anupstanding arm 11 at itsrear edge, said: arm being formed with anaperture 12 and a slot l3 leading therefrom upwardlyrthrough the upperend of said arm. In applying-{the backsaddle to the shank of the frontsaddle, the latter is held in an upright position, or so that the shankwill extend at right angles to the back saddle, with the peripheralrecess 5 facin the inner side of the arm. The shank is t enmovedlaterally to engage one of the opposing fingers 14 in the recess 5 andthe knob 4 disposed in the aperture 12, as depicted indotted lines inFig. 3. The-front saddle is then swung down to the full lined positionand dropped from out the slot 13 into the aperture 12 in which latterthe shank is freely rotatable and slidable. The front saddle is thenturned to bring the saddle proper into a downwardly-facing position, theextent of rotation in this instance being substantially a quarter turn,as indicated in Fig. 2. p

In its operative position, the back saddle is supported off the shank bythe wall 15 formed on the opposite end of said back saddle. When it isdesired to seat the saddle on the middle roll, the saddle is turned anadditional quarter revolution to brin its slot 13 in alinement with thelug 8, w ich latter is disposed on the opposite side of the shank fromthe recess 5, and shifted longitudinally of the shank past the lug tothe dotted line position indicated in Fig. 1.

It will therefore be noted that the saddles are angularly related inapplying the back saddle to or removing the same from the shank, theswinging movement being in a plane longitudinal of the shank so thatthere is practically no possibilit of either becoming disengaged onefrom t e other.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is 1. In a top roll saddle construction, afront saddle having a rearwardly extending shank formed on its extremitywith an enlarged knob and a recess adjacent thereto on one side of theshank, a laterally extending lug formed on the opposite side of theshank and spaced forwardly of the recess, and a back saddle having anupvvardly extending arm formed witha shank receiving aperture, thelatter having an entrance slot leading through the upper end of thearmto provid sp ced ng r f r g g ngin the'f recess of the shank on removingandmount:

ing the back saddle over theknob from and to operative position ontheshank.

2.-In a top"ro1l sadd1'e' construction, a front saddle having arearvvardly extending shank terminating in a knob and formed Witharecess adjacent the knob, a lug provided on the shank in spacedrelation to the recess and staggered relative thereto, and a back saddlehaving an upstanding armbifurcated at its upper end to engage in theshank recess'to' permit movement of the backsaddle from and to operativeposition ontheshank;

' 3'. In'atop r011 saddle, a front saddle and a back saddle, holdingmeans on the'back Copies of this patent may be obtained for saddle, andmeans on the front saddle engageable With said first named means whenthe saddles are at relatively right angles,

said means being "formed to efiect locking of the saddles upon relativepivotal movement 'following said right angular disposition.

'eLJ'In a top roll saddle construction, a pair of saddles, one having ashank formed With a side recess adjacent its end and the other having anopening receiving the shank and defined by an overhanging part movableinto theiecess to permit the end of the shank being swung through theopeningto, disconnect the saddles. v

In testimony whereof I have signed my name to this specification in thepresence of tWo subscribingwitnesses.
